A This invention relates to improvements in window construction'and more particularly in easement window construction. I One'great objection to the use of ordinary doubleand easement windows is. that it is diiiic t to render them secure against wind and rain and in the case of ordinary easement windows, s ince the windows are usually hung on vertical pivots at their sides,

'10 the sashes must'be heavier than for counterbalanced windows, because of the added strain. Double hung windows are relatively dicult to clean, the maximum area ossible for ventilation is only one-half of t e area of the windows and it is dilicult to properly lglulate ventilation when ordinary vertiy dpivoted easement windows are employe An object of this invention is to combine 2 many of the advantages of the double-hung and easement windows in an improved window construction. v

Another object of the invention is to provide a window construction' having the, out- 2.5 ward appearance of either an ordinaryA double-hung window or a easement window but made up of a plurality of independently swingable sashsections.

Another object is to provide la window construction made up of a plurality of independently removable sash sections.

Still another object is 'to provide a. window construction comprising a lurality of sash sections which may be quie removed from the window frame, leaving t eopening in the frame unrestricted.

Still another object is to provide a window construction which has the4 advantages of double hu windows but obviates the need 4 of sash cor s, weights, pulleys and the like.

Other objects and advantages of this invention will be apparent during the course of the following detailed description, taken in connection with the accompan Adrawings, forming a part of this spec' cation and in which drawings Figure 1 is a perspective view of a win- `dow construction embodying the improvement, as viewed from the outside.

Figure 3 is a fragmentary vertical section thru the improved window construction. l lFigure'fl is a fragmentary elevation of the. improved window construction viewed from the. inside, parts being broken away to better illustrate portions of the construction.

Figure 5 is a fragmentary cross 'sectional view of -that portion of the improved win-1; dow construction showing an improved pivoting device inplace. y

F1gure`6 is a perspective view of the im proved pivoting device shown in Figure 5. In the drawings, `wherein like reference characters designate si-nilar parts thruout the views, A desi nates a portlon of .a-ebuilding, B a window rame C the improved win dow construction and l) the novel pivoting' device for the improved window construc tion. 'v v The portion of the building A may comprise any part of such a structure,`and itshould be understood that the terml window includes windows in doors and the. like.

The window frame or casing B`m`ay include a sill 11, blind-hanging Stiles 12, side the place of conventional gllley stiles, a window head 14, a cap memr 15 and'a mullion 16. 'As for the improved window construction C, the same include's'a plurality of independently pivoted sash sections 20 and 21, provided with novel rails.

r Inthe example shown, the upper rails 220i both sections 20 and 21 are provided with4 transversely c onve'xed portions 23 extending the length of the uplper side of the rails. The pivotal axes of the sash sections are co-axial with the pivotal axes of-their convex edges. It will vbe noted however, that these axes do not intersect the lateral medi-al line of the sash sections but are locatedso that the convex portions of the upper rails plroject beyond the remainderxof s own at 24, while on the opposite side the convex portion merges into .the remainder vof the rail .as shown at 25. At either end these kupper rails are provided with sockets 26 'and bayonet slots 26 com- 1m l municating with the sockets, for .a purpose .to accommodate screws 53a later set out. The lower rails 27 of the sash section 20 overhang the upper rails of their adjacent sash sections as shown at 28 and this overhanging portion is provided with a concavity 28 extending the length of the lower side of the lower rails. The pivotal axes of these concavities are co-axialwith the pivotal axes of the convex portion, but instead of the concavity extending transversely of the whole lower edge of the lower rails 1t merges into a rounded off portion shown at 30. Both the flat and concaved surfaces of the lower edges of the lower rails are covered by a suitable packing or weather stripping 31 shaped to conform to the convex surf-aces of the upper rail 22 and the rounded surfaces of the lowery rail 27. The packing which may be of rubber maybe suitably secured to th-e lower edges of the lower ra1l s as by screws 32 or the like. The lower ra1l 35 of each sash section 21 is preferably at at vits extremity 36 and both its outer and inner faces37 and 38 are fiat as shown in Figure 3, and this rail is preferably not provided with a packing. The central openlng in each sash is, of course, provided with a 39 or other covering for thev pane of glass opening, secured in place by any -approved means.

As an additional means for excluding air etc., and providing a stop for the sash sections, a packing 40 is provided secured as with a backing strip 41 and screws 42 tothe side stiles 13 of the window frame Bas shown in Figure 3. If the mullion 16 is included in the frame structure, additional .p-acklng 40, backing strips 41 and screws 42 are provided to be similarly secured to the mullion. These individual sash sections may be of wood, wood and metal, or entirely of metal since they are individually small and comparatively light in weight even l1f of met-al and can be handled readily.

From Figure 3 it will be noted that a socket member 45 and associatepacking 4 6 is., secured tothe window head 14 providing a socket for the uppermost sash section.

`Now as for the novel pivotinu' device D, the same includes an elongate tubular member or housing50, o-pen at one end 51 and from which end extends radially an attaching wing 52 provided with perforations 53 or the like for the (purpose of securing the device to the sash section. lThis wing 52 has itsv outer surface flush with the end of the housing 50. The housing is slotted longitudinally by a bayonet `,slot 54 having lock slots 55 and 56. A pivot pin 57 is loosely carried in the tubular member and has a length less than the length of -the bore of the tubular member so that between the closed end 58 of the latter and the innerfend of the pin 57, a coil spring 59 or the like may be positioned to bear against the end 58 and pivot pin 57 and urge the latter outwardly so as to project thru the open end 51 of the tubular member. A handle or pin 59a or the like may be secured as by screw threads to the pivot pin to extend radially therefrom and project thru the slot 54 for 'the purpose of manipulating the pivot pin in connection with the slot, as is obvious. It is preferred that the outer end of the pivot pin be chamfered as at 60.- Two of these devices are secured to each sash section by inserting the tubular member 50 into each of the sockets 26 in the sash sections with a pin 59a projecting thru each bayonet slot 26a in a sash section, with the slot 26a aligning with the bayonet slot in the tubular member. As heretofore stated, the device may be secured to the sash sections by means of the wing 52 and screws 53, so that the outer surface of the wings will be -lush with the ends of the sash sections. These pivot pins 57 are adapted to extend into bearing members 61 which may be carried by the side stiles 13 or mullion 16, with the outer end 62 of the bearing members flush with the outer surfaces of the stiles and mullion. Each bearing member is provided with a socket 63"communicating with the outer surface, and receiving the end of the pivot pin. The bearing members 61 may be secured to the stiles and mullions as by screws 64 or the like, all as shown in Figure 5.

In assembling the independent sash sections after the bearing members 61, the socket member or members 45 and the packing 40 is in place, the pivot pins 57 are manipulated so as to retract them by means of the handle or pins 59a and bayonet slot, yand the sash sections inserted between opposed side Stiles or a side stile and a mullion and when the openings in the members 50 and 61 align,

the lpivot pins are released and the ends projected into the bearings by the springs 59. The pivot pins may be retracted and the individual sash sections quickly removed when desired. j o

Itwill be seen, particularly from Figures 2 and 3, that the individual sash sections may be swung on their pivots but that when the sections are down or closed, the packings 46, 31 and 40 will exclude air and the like. Any suitable means may be provided to lock the individual `sash sections in any position desired, and the individual sash sections may be manipulated in any way desirable such as openingthe lowermost sash and the uppermost sash sections to create a draft. In cleaning the window, the individual sash sections` may be removed one by one and cleaned or the outer sides of the panes may be cleaned thru the opening provided by swinging open the sash immediatelyabove that one to be cleaned.

Various changes may be made to the form of invention herein shown and described, without departing from the spirit of the invention or the scope Aof the following claims.
